Some people love you exactly as long as you have a car.

Convenience gets mistaken for affection by both sides. When you are the one with the car, the money, the free time or the space, the attention you receive is real and may be attached to the resource rather than to you. That is not always cynical, since people drift toward whatever is easy. You tend to find out only when the resource is gone.

Notice who calls when you have nothing useful to offer. Say you cannot drive this once and watch who adjusts without complaint. Keep the ones who are good company either way.
